Given numbers are 847,138,941,738,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,138,941,738,641 is 8671919967018.
Find LCM of 847,138,941,738,641 with Prime Factorization
| 2 | 847, 138, 941, 738, 641 |
| 3 | 847, 69, 941, 369, 641 |
| 847, 23, 941, 123, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 847 x 23 x 941 x 123 x 641 = 8671919967018
Therefore, the lowest common multiple of 847,138,941,738,641 is 8671919967018.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
847 x 138 x 941 x 738 x 641 = 52031519802108
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
847 : 1, 7, 11, 77, 121, 847
138 : 1, 2, 3, 6, 23, 46, 69, 138
941 : 1, 941
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,138,941,738,641, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
138:2x 3x 23
941:941
738:2x 3x 3x 41
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 52031519802108/(1x6)
LCM = 52031519802108/6
LCM = 8671919967018
Thus, we can understand that the LCM of 847,138,941,738,641 is 8671919967018.
